I've taken fo ti off and on for years now. I play sports, and have found fo ti to be excellent for sore knees and stamina levels.
I have tried many brands as well, and only tried this one because my favorite was out of stock. Though the name "Paradise Herbs" seems kind of "cheesy," it, I believe, is a powerful extract. And my body seems to respond very well to this particular brand. So I am going to buy another bottle.

I like being active: enjoy jogging, bowling, and basketball. I suffer(ed) from a painful case of bursitis due to the repetitive use of my arm (elbow). The mere extension of my arm would cause pain and subsequent swelling in my elbow.
After researching herbal alternatives to steroids and NSAIDS, I decided to try this Boswellia brand (in combination with turmeric - curcumin). And over a period of, say, a month and a half, the pain and inflammation in my elbow has lessened greatly; so much so, that I can once again play basketball on consecutive days, with little to no swelling or pain. Unbelievable!
I am so happy that there are natural options available to us. And though this is not a quick fix, Boswellia and Turmeric do slowly but surely work (if you are patient, and do not aggravate). Their effectiveness is long lasting too!
